Astronomers have just discovered UFOs - but don't reach for your tinfoil
hat just yet, Neatoramanauts! They're talking about Ultra-fast Outflow
found at the center of black holes, which, if you think about it, is actually
far stranger than your everyday Unidentified Flying Object:

Black holes are surrounded by a million degree X-ray emitting disk
of gas. This gas is sucked into the black hole and powers it. Some of
the disk material, however, escapes and is redirected outwards as a
jet of energetic particles.

These jets do not explain the link between black holes and bulges,
though. So astronomers went looking for a new kind of black hole outflow
that was somewhere between these particle jets, which travel at half
the speed of light, and known outflows that travel much slower.

Now, Francesco Tombesi and his colleagues have found that new type
of outflow. It is called “ultra-fast” because it is faster
than already-known outflows, but slower than jets. UFOs could explain
the link between black hole and bulge size. They contain more mass and
have a wider opening angle than jets do, so should interact more with
the stuff between stars in the galaxy.
